STITCH AND WELT RUBBING MACHINE.

Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed May 20, 1904. Serial No. 208,921.

To all whom, it may concern:

Be it known that I, FRANK R. RnvARn, a citizen of the United States,residing at Portsmouth, in the county of Scioto and State of Ohio, haveinvented new and useful Improvements in Stitch and Welt RubbingMachines, of which the following is a specification.

This invention relates to certain new and useful improvements in stitchand welt rubbing machines, and has for its object to provide a novelmachine of this character which will permit the welt and stitch to berubbed rapidly and with great ease in manipulation, while at the sametime finishing ofi this portion of the shoe in a highly-satisfactorymanner.

WVith these ends in view the invention resides in the features ofconstruction and combinations and operations of parts hereinafterdescribed, and particularly pointed out in the claims.

In order that the invention may be clearly understood, I haveillustrated the same in the accompanying drawings, in which Figure 1 isa front view of a machine constructed according to my invention. Fig. 2is a side view of the same. Fig. 3 is a sectional detail view of aportion of the operating mechanism, and Fig. 4 is a detail viewillustrating ashoe in position to have its welt rubbed.

Referring now to the drawings, 1 indicates a standard in the base 2 ofwhich is mounted a belt-driven pulley 3, imparting motion by a band 4 toa smaller pulley 5, mounted in the upper part of the standard 1 on ashaft 6, which it rotates. Secured on the shaft 6 is an eccentric 7,surrounded by-a strap 8, which carries an arm 9. Said arm is pivotallysecured at 10 in the upper bifurcated end of a crank-arm 11, formedintegral with a sleeve 12, which is journaled on a pin 13. The sleeve 12has an integral depending portion 14, from which projects outward a footpiece 15. Mounted on a pin 16, carried by this foot-piece, is therubbing-tool 17, the tool being held on the pin by means of aleaf-spring 18. The working face of said tool may be either smooth orcorrugated, as preferred or as the nature of the work to be performedmay render desirable. Suitably supported on the front of the standard 1is a casting or support 19, affording two bearingsa smooth bearing 20and a screw-threaded bearing 21. Engaging in the screw-threaded bearing21 is a hollow screw 22, having on its lower end a non-circular head 23,by means of which it may be turned.

24 indicates the shoe-support or table,which is pivotally mounted on theupper end of a plunger 25, so as to be capable of adjustment.

26 indicates a plunger-rod the upper end of which is screwed into thelower end of the plunger 25. Surrounding the rod 26 and confined betweenthe lower end of the plunger 25 and the upper end of the adjusting-screw22 is a coiled spring 27. The plunger-rod 26 passes through the hollowscrew 22 and has its lower end portion screw-threaded to receivelock-nuts 28. Secured to the lower end of the plunger-rod 26 in anysuitable manner, as by means of a staple 29, screwed on the lower end ofsaid rod, is a pull-rod, 30, connected to a treadle 31, mounted in thebase 2.

The operation is as follows: The pulley 3 revolving, the eccentric 7will impart a reciprocating motion to the arm 9, which will in turnimpart an oscillating movement to the depending portion or tool-holder14 about the pin 13 as a center, as will be clearly understood. To placea shoe in position, the operator depresses the treadle 31, pulling thetable 24 downward, and then places the shoe upon said table and allowsthe treadle to rise. This brings the extension or welt of the shoe in aposition to be engaged by the rapidlyoscillating rubber 17, as indicatedby Fig. 4, and by suitably manipulating or turning the shoe the entirestitched portion of the sole may be rapidly rubbed and a high finishimparted thereto. By turning the screw 22 to raise or lower it thetension of the spring 27 may be regulated, which in turn regulates thepressure at which the shoe is held against the rubbing-tool. Byadjusting the lock-nuts 28 the distance between the table 24 and therubbing-tool may be regulated according to the thickness of sole to berubbed.

Having thus fully described my invention, what I claim as new is 1. In amachine of the character described,in combination with a shoe-support, anon-rotatable rubbing-tool associated therewith having a working endportion projecting outwardly at an angle to the body of the tool andadapted, when a shoe is placed with its sole upon said support, toextend between the upper and the sole, means for causing the saidshoe-support to be pressed upwardly toward said rubbing-tool, and meansfor oscillating said rubbing-tool in a direction longitudinallycontinuously oscillating said tool-holder in a direction longitudinallyof the stitches to cause the rubbing-tool to rub down the stitches onthe sole.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

FRANK R. REVARE.
